Letters Patent N o. 96,748, dated November 9, 1869.

IMPROVEIVIENT IN PENCIL-SHARPENERS.

The Schedule referred to in these -Letters Patent and making part of thesame.

To all Iwhom 'it may concern.-

Be it known that I, WILLIAn N. XVEEDEN, of Boston, in the county ofSublk, and State of Massachusetts, have invented an ImprovedPencil-Sharpener; and I do hereby declare that the following, taken inconnection with the drawings which accompany and form part of thisspecitication, is a description of my invention, suicient to enablethose skilled in the art to practise it.

My invention relates to the construction of that class ofpencil-Sharpeners in which a knife-edge is combined with a conical ortapering socket, in such manner that by inserting the pencil end in thesocket and rotating it, the pencilpoint is eut away and sharpened by theknife, the chips escaping through a suitable throat.

My invention consists, primarily, in hinging the cutter-blade in suchmanner that it may be swung ont. from the socket-piece, for the-purposeof whetting the edge.

The invention also consists in making the pencilsharpening blade with anink-erasing point, and in embodying with the sharpeneran erasing rubber.

The drawings represent an instrument embodying my improvements..

A shows the pencil-Sharpener in .front view.

B an edge view of it.

C shows the position ofthe blade when thrown out for sharpening, or foruse as an eraser. v

a denotes the socket-piece, having the conical recess or tube forreceiving the end of the pencil.

From this socket-piece projects a long ear or bladecase, b, in which isa slit, c, for receiving the blade d, said blade being jointed to theend of the ealr by a pin, e, its back resting against the inner wall orbonndary of the slit, and its front or cutting-edge projectingbeyond-the front edge of the ear, and forming one edge of the throat f,through which the chips escape.

In ordinary pencil-Sharpeners the blade is fixed relatively to thesocket and throat, and, as the cuttingedge of the blade is comesuseless.

To remedy this lI so hinge the blade that it can be swung ont from theease b, (as seen at 0,) in which positionY the surfaces of the -blademay be presented to an oil or whetstonc, or other suitable reducinginstrument. By this means the edge may alw. ys be kept keen, giving the'than is possessed by those having fixed blades. If the blade becomesreduced in width by sharpening, a small chip or thread can be pressed tothe back of the blade-receiving slit, to bring the cutting-edge forward.

At the end of the blade I make a curved cuttingedge, g, which, when theblade is thrown out, as seen at O, forms an eraser for erasingink-lines.

From the end of the case b, opposite the hinge-pin e, I extend a shank,It, upon which is pressed a hollow rubber, t', for erasing pencil-marks.

A combined ink and pencil-eraser and pencil-sharpener is thus made invery compact shape, without material increase in cost over commonpencil-sharpeners, and having a far greater degree of utility, even as aSharpener, than any pencil-Sharpener now made.

I claim, in combination with the point-receivingsocket or socket-piecea, the hinged blade d, constructed and applied thereto, s0 as to serveas a sharpener when closed and as an eraser when open.

Also, a pencil-Sharpener, having such a hinged sharpening anderasing-blade, and a rubber, i, applied to its shank or handle h, allsubstantially as shown and described.
